Greetings -
I'm not sure if this is a bug or if I'm unknowingly doing something that I
ought not, but I started encountering this exception when I switched my
site from debug to production:
Traceback (most recent call last):

Here's the Referral model for your reference:

Again, this works perfectly in DEBUG mode but begins firing off exception
emails to me the minute I switch off debug. I've been hitting my head
against the wall for the better part of the day trying to figure out what's
going on. Any help would be greatly, greatly appreciated.
Thank you!
Derek
